To all ZUZLOTH/ Z Z ijH/(L'y concern.-

Be it known that l, CLIFFORD MB, a citizen of the United States, and athe county of (look. and State of Illinois, have invented. certain newand useful linpriwenicnts in Steam-Engine-s; and I do hereby declarethat the fol lowing full, clear, and exact description. of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form. a part of this specification.

This invention relates more particularly to l l l l l 1 l l l i l l line9 9 of Fig. 1. modified construction, of the valve-gear. Fig. 11illustrates a detail of construction.

As. shown. in said drawings-mid engine (JOll'lPllSGS a base or bed A,having secured at each end thereof uprights or standards a a Alongitudinal hollow shaft B is journaled on the standard a, which ischambered toprovide inlet and exhaustchambers, and said shaft is slottedlongitudinallyin said inletpassage to admit steam into said shaft. Inalineincnt with said shaft and rigidly secured on the standard (1 1s anon-rotativc steam-engine'-provided with a plurality of "shaft B,provided at its end adjacent to the reciprocating pistons in which thecylinders, with the pistons, rotateabout a fixed shaft.

Heretofore many different types of rotary and reciprocating engines havebeen devised, in all of which the vibration caused by the operation ofthe engine has been oonsiderable, and this, taken. in connection withthe forms of valve-gear used, has tended-to decrease the efiicioncy.

The object of this invention is to provide a perfectly-balanced enginerotated upon its center by oppositely-acting balanced pistons operatingupon a non-rotative crank-shaft.

It is also an object of the invention to pro vide a simple andoasily-governed valve mechanism whereby the ports of the respectivecylinders are controlled with slight relative movements of ti e valves,operated by a single governor affording the effect of a double valve inordinary engines.

ho invention consists in the matters heroii'iaftcr described, and morefully pointed out and defined in. the appended claims.-

.ln the drawings, Figure "l. is a central vertical section taken l ngitudin ally of the driving shaft of a device embodying my inven: tion andshowing the non-rot ativc shaft and crank in elevation. Fig. 2 is asection taken on lino 2 Z'of Fig. l and illustrates the operation of thegovernor. Fig. 3 is a section taken on line 3 S of Fig. i. Fig. l is asection similar to Fig. 2, but illustrates a dif- 'fcrent position ofthe valve. l i lar section taken closer to the disk and with the springsand governing-bars removed. Fig. ii is an enlarged detail section takenon line 6 6 of Fig. Fig. 7 is an elarge section taken on lino 7 .7 ofFig. 4. fragmentary deta l illustrating the or of the pistons. i is asection taken inner end of the shaft B with a crank b.

Rigidlysecured on the inner end of the shaft B is a circular plate ordisk C, provided with with t e bore of the shaft B and extend from thecenter of said disk to near the periphery and opening therethrough onthe side adjacent said shaft, the apertures or ports bein indicated byc. In the drawings four. of sai passages or ports are shown, one foreach of the cylinders of the engine, though obviously the number of suchpassages corresponds with the number and arrangement of the cylinderswith which the engine is provided. Each of said openings 0, whileapproximately rectangular in. form, extends upwardly on one sideradially of the disk, thus providinga somewhat L-shaped orifice havingits great-.

est length radially of the disk. Between s aid orifice c and theperiphery of said disk a port or opening 0 is provided therethrough,which I is also rectangular, having its greatest length is a simi- I ata right angle with the radius passing through the extension of theorifice 0. Each of said ports 0 registers with a corresponding port (1in the outer ends of cylinders D, D, D or D in the present construotlonshown as four .in number and which are rigidly bolted at rightangleswith each other to the Fig. 10 is a detail of a assages thereinwhichcommunicate' face of said disk C with the ports 01 thereinregistering with the ports 0, as before described. in the constructionshown said cylinders are integrally connected at their inner ends andare rovided with cylinder-heads d d d d rigid y bolted thereto.

Jour t upon. the non-rotative shaft B is a cas ig D, whio fitscloselyagamst and is boited to the inner ends of said cylinders, niingtogether therewith and the disk or J a closed chamber at the inner endsof a lubricant thereinto, and a pin b is secure in said shaft andextends into said channel and acts to deflect the oil onto-the shaft asthe engine revolves. Within each of said cylinders is provided areciprocating piston E E E E provided with piston-rings 1n the usualmanner. Piston-rods e e 42 are pivotally connected at one end .with theinner end of each piston thereof and at the other end are journaled onsaid crank b. Said crank b is cylindric, and a washer b, havin a greaterdiameter than the crank, is secured on the end thereof by means of abelt 5 which extends through the crank and'is provided with a nut at itsend, which acts to draw the washer inwardly to the crank. Journaled vonsaid crank are inwardly-facing flanged cones B B", which engage,respectively, against the crank-arm and against said washer and afford abearing for the inner ends of the piston-rods, which,.'as shown, ,isextended laterally, forming a head affordingshoulders e at,

ri ht an les with the piston-rods on the inner side and on the outershaped to engage against said cones.

Continuous rings 12 b engage over the laterally-directed shoulders e ofthe piston rods and within the flanges of the cones and serve to engagethe piston-rods to the crank,

permitting considerable freedom of movement as the cylinders revolvearound said crank, as shown in Fig. 3, and permitting wear on the partsto be taken up by the adjustment of said bolt 6 Surrounding the innerend of said tubular shafts B and closely I adjacent to the disk 0 is aneccentric F,

which act uates the valve-frame G and is provided with an integralsleeve f, 0 en on its under side and extendin outward y therefrom. Saidsleeve is provided with a peripheral flange f at its outer end, which isrigidly bolted to the walls of the exhaust-chamber and acts to hold saidsleeve a'nd eccentric from rotation. A tightfcasing 0 having a diameterequal to the diameter of the disk 0,

is rigidly bolted at its periphery to said disk,

as'shown 1', and a' casing comprising the two similar sections Q isbolted thereto and engages closely aroun said sleeve and provided withan cutwardl. opening seat ing-box or gland.

adapted to receive the inner end of a sleeved follower-nutfi, threadedon said sleeve adjacent to said flange f and which acts, together withthe seat in said casing, to afford a stuffsleeve g extending therefromof less outer Mounted on' said eccentric F is a valve -ca-rry1ng frameG, comand of substantially the same inner diame ter as the hub. Said.hub fits closely upon the eccentric F, and the valve-frame mtegraltherewith is substantially rectangular in form and is provided at thecorners with circular apertures g g opening therethrough and eachsurrounded by a raised flange. Within each of. said circular aperturesand rigidly secured in the disk 0 are the stud-bolts 9 on each of whichis journaled a roller 9 which tracks on the inner wall of saidapertures, thereby forming at each corner of the valve-frame G aneccentric guide which acts to limit the movement of said valve-frame toa gyratory motion about the center of the disk and in the direction ofthe successive ports opening into the cylinders. Along each side of saidvalve-frame G, as shown, a slot 9 is provided, which at all times ismaintained at a right angle with the respective inlet-pas- I sages ofthe disk by means of the eccentric guldes located at the corners of saidvalveirame. Engaged in each of said slots in posi- -tion to control therespective ports opening throughsaid disk C are the valve-plates H H H Ht Each of said valve-plates is provided with two apertures or portstherethrough, one of which, its, is rectangular in form and positionedto the right of the center of the valve and acts to equalize thepressureon the valveplate, and the other, h, located at the left of thecenter, is elongated radially of the disk and at its top is extendedlaterally to correspond with the length of the port 0 in said disk andacts to convey steam from the ports 0 to the ports 0; Said valve-platesare each at the inner end on the under surface shaped IOO complementallywith the adjacent sides of I the valve-frame G'and interfittherewith andare adapted to slide thereon laterally. The

said valve-plates are also each provided with an inwardly-directedarm hh h 7L3.

A governor-ring I is seated on the sleeve g of the valve-frame andprovided with integral arms ii" i i the arrangement of which correspondswith the passages in the disk C and which are connected with thecorresponding arms of the valve-plates by means of stud-bolts, one ofwhich extends downwardly through a radially-slotted aperture in each ofthe arms of said ring and is provided with a sliding blocktherein totake the wear. and is rigidly secured to the inner end of the arm on thevalve-plate. This construction acts to slide all the valve-plateslaterally of the valve-frame when said governor-ring I is. slightlyrotated thereon and affords meansfor governing the engine byrestricti-ngor varying the inlet-ports thereof by such movement. To enable this tobe automatically accomplished, governor-bars K and K are pivoted onthevalve-frame,'as shown, near the center ofa plate 7c", integral with saidframe and positioned above the apertures g as shown in Fig. 4. Said barsare of a length equalizing the pressure, as

to extend somewhat past the scracent recesses g at the outer entl of rooor linl; 7c, the other end of which extends a right ngle therefrom andis civoteii onthe adjacent arm by means of the pivot hclt connecting thevalve therewith of the governor-ring i. Adjustahly engaged with andconnecting the oppositely- CllSPOSGd extremities of said governor-barsare strong coiled springs 13, which act normally to hold the free endsof said governon hare inwardly, as shown in Fig. 4:, iv ich positionthevalves afford a maximum open." ing of the various ports during theoperation of the engine, Adjustahly secured on each of'the governonharsK and K" are the weights it, each provided with a set-screw adapted tonositively iii: the same upon the bar.

At each side of the valve-plate H H H5 H respectively, are provided theraised ribs c integral with the (list: C and in height approximatelyequal to the hearing-face of said. disk. Said ribs serve as supports forvalvepressure plates M, one of which is rigidly bolted on said ribs 2above each valve and is provided with recesses m m on the under side tocorrespond with the apertures h 7t through the valve-plates, affordingmeans for is usual in such devices. As shown, a plurality ofrilos 'm areprovided on each pressure-plate, extending from each end thereof, andthereby increasing strength without materially increasing weight Thesteam-supply pipe is connected in any desired manner with the passage Nin the top of the standard or pedestal a and communicates wth the shaftB through the slotted apertures opening thereinto, as shown in Fig. 1. Acap N, cored to afford;- a part of the steam-inlet passage, is securedabove said inlet-apertures and rigidly bolted to the perlestal orstandard and recessed at each oi' the inlet-passage to afford, togetherwith the follower-nuts 'It a Q'iands to revent the e fl r a cape orsteam tl'iereiroin.

The operation is as follows: The engine, as-

sernhletl and mounted 2n described, is per' fcctiy balanced, and. theoppositely rlisposetl pistons operating simultaneously upon a stationarycrank act to rotate the engine asa whole. 4W hen steam is admitted throuh the sliat't B, it passes through the passages in the (list; (1,through the valve plate, ancl from thence to the cylinder oi which theinlet-port is open, acting to reciprocate the piston, and therebyrotating the engine, as heiore' (lescrihed. lnasmnch as the eccentric.l, which actuatcs the valve-frame, is stationary, the rotation of theengine around. the same causes gyratcry movement of the saidValve'iramc, carrying the valves therewith and providing maxi openingand coinnlete closure of the v an diesel-centers permitting tit steam tothrough the valves successively middle of the to the cylinders. theirother enrl and at its integral e a sis The governor-ring I, with. arms,hemg carried on and mow and emits are each pivotally connected with ablewith and also independently oi the valveireine and having the armsthereof pivotally connected with the respective valve-plates causes alithe valves to be simultaneously shifted laterally oi the ports when.said ring is partly rotated on the tram e. restricting or cutting oilthe inlet-ports, and thereby governing the engine. This is accomplishedin, part by the peculiar form of the port and openings and the aperturesin the valves, clearly shown in l 2, in which the valves are shownshifted to a'fl'orrl a positive cut-oll for the steam through thevalves. This movement is caused by the centrifugal action oi thegovernor-bars K K, pivoted on diametrically opposite sides of thevalve-frame G and each connected at its free eml with o'ipositcly-rlisposed arms of said governing-ring and held norm ally attheir inward adjustment by strong spiral springs k which, as shown, areadjnstahly engaged on. the free eml'oi each governonloar and areattached at the other end to the pivoted endv of the oppositegovernor-her. T he adjustable weights in" obviouslv permit the governorto he set to cut oli centrit'ugally at any required rate of rotation,

4 centrifugal force acting to throw the governorbars outwardly, shiftingthe governor-ring and the valves connected therewith laterally withrespect to the valve-frame, as shown in Fig. 2. lhc steam from saidcylinders exhausts through the ports (1 antic into the casi'ng with thereturn stroke of the piston and from thcncepesscs through the sleevef ofthe. eccentric into the 'exliaustchamher a, as shown in Fig. 1. Theconnection of the piston-rods with the crank aiiords great strength,

slight friction, and ease of adjustment, inasmuch as the cones, which(lo not meet each other on the oranlgmay be drawn inwardly hy the belt 5affording any desired adjustient of the hearing of the rings and theends of the piston-ro ls against the same.

(loviously instead of the grooves in the sicles of the valyc-irame thevalvcmlates may, if preferred, heconnecterl therewith by means of links721 one of which connects each side-of the valve with the valve-frame,as shown in big. 10. Said links permit the valve-plates to be drawnlaterally of the valve-Frame by the governor and to afford a cut-cit, asbefore (lescrihed v @hviously many modifications and variations ofdetailsof construction may he made in embodying my invention and thenumber and arrangement of cylinders features of construction may bevaried without departing from the principles of my invention.
